refactor(recaptcha): migrate from reCAPTCHA v3 Enterprise to v2 widget-based implementation

- Replace enterprise.execute() with widget.render() approach
- Add reCAPTCHA v2 widget initialization and response handling
- Add debug validation state display for form debugging
- Add production build script using cross-env
- Add react-perf-devtool for performance monitoring
- Update all reCAPTCHA utility functions for v2 compatibility
- Maintain backward compatibility with legacy functions

The migration from reCAPTCHA v3 Enterprise to v2 provides better user experience with visible checkbox verification while maintaining the same security validation. The new implementation includes proper widget lifecycle management and fallback handling for cases where reCAPTCHA is unavailable.
